Upon returning to my truck after enjoying a tasty repast at Noodles & Company, I noticed the restaurant's illuminated signage reflected in my side view mirror.
Wait a minute! The reflected message was not "reversed" in typical mirror fashion. I turned to see the signage as it appears on the building.
Once suitably ensconced in the driver's seat, all was again right with the world. The letters were reversed as they should be.
What is your explanation?
[A few years ago, I sent this optical oddity in to Click and Clack, the Tappet Brothers (NPR's Car Talk personalities, Tom and Ray Magliozzi). But it was apparently too lousy for them to use, despite being quasi-automotive! Oh well.]
